These individuals may claim deductions for meals and lodging per "legislative day" in the amount of per diem allowance for federal employees in effect for the tax year. The portion of this per diem allowance which is equal to the daily expense allowance authorized for state legislators in Iowa Code section 210. may be claimed as an adjustment to income. The balance of the per diem allowance for federal employees must be allocated between lodging expenses and meal expenses and is deductible as a miscellaneous itemized deduction. However, only 50 percent of the amount attributable to meal expenses may be deducted for tax years beginning on or after January 1, 1994.
